Description
Standard ground glass joint stoppers made of polyethylene (PE) close laboratory glassware fitted with NS 19/26 standard taper joints. A blue insert marks the size clearly, helping staff select the correct stopper when several joint formats share the same workspace. The PE construction offers a lightweight, practical seal for flasks, receivers and adapters used in general chemistry, teaching and preparative routines. Each pack holds 10 pieces and has a weight of 0,080 kg, suitable for bench-side stocking and shared lab stores. Colour-coded inserts support faster setup and fewer mismatches during multi-step procedures. These stoppers from manufacturer DWK Life Sciences provide temporary closure against dust and short-term evaporation while vessels are handled or held between process steps. They belong to the standard range of stoppers with taper for everyday labware and are intended for routine sealing tasks rather than specialised vacuum or long-term storage duties.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about Standard ground glass joint stoppers, PE, NS 19/26, insert blue, 10 unit(s)
What is this article?
Standard ground glass joint stoppers, PE, NS 19/26, insert blue, 10 unit(s) is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Ground-joint glass stoppers, inside Stoppers, caps & closures, in Labware.
A ground-glass stopper matches a ground neck of a stated joint size. A 14/23 stopper does not seal a 29/32 neck. The stopper is part of the flask's seal, and a chip on the grind is a leak.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
